I'm working on a project to build a controller for an industrial robot arm motoman up 6. I would love to see suggestions. Ben looking at robodk it's a bit expensive. The maker of ar4 robot arm says his software will work. I'm thinking ros simulink and Matlab. The survos have encoders so I've been looking into projects with pwm survo drive extension adafruit seems a bit small. So I've been finding some Arduino pwm survo drive extensions. I have compleat documentation of the robot arm specs and io. I've seen some GitHub stuff for motoman up6 have yet to delve into it all. Just eager to get some quality suggestions. So here it is. Some of the industrial survo drivers for encoders price is more than I paid for the robot.
